Choosing the right DC power supply for your application requires definition of some basic design specifications: voltage range, current range, number of outputs, power cleanliness and programmability. In general, the higher the output voltage and the lower the ripple, the more expensive the DC Power Supply. Multiple outputs and programmability features will also add to the cost. Mid-range DC power supplies can be linear or switching and could range in price from $200 to $1,000.
High voltage dc power supply is ideal for
electronics hobbyists and basic electro-mechanical applications where only raw
power is required. It is likely that the devices being powered in these
applications already have power-conditioning features that eliminate the need
for precision input power. Low power, single output, DC power supplies range in
price from $50 to $200.
Before making your low voltage high current dc power supply
purchase, be sure to consult the manufacturer and thoroughly understand all the
specifications of a particular product. Choosing the best and most economical
DC Power Supply for your application does not have to be a complex and
time-consuming task. By identifying your design parameters, you will quickly
narrow down product selection to a niche class of products from only a few
manufacturers.
